I have to admit I tend to prefer actual time zone names like
"America/New_York" over acronyms or offset values.  However, I can see
the dump/restore problem with such names.

Parenthetically, I often use airport codes that map to time zones in my
own calendar.  I would argue that on a global scale airport codes are
actually more useful than abbreviations like EST, assuming you don't
need to designate whether daylight saving time was active, e.g. EST vs.
EDT.
